- That's the LC and LC II. The video system in the Falcon gets its data in
- 32-bit chunks, not 64-bit (that's the TT). While video access is going on,
- the CPU can't use the bus; but, in the LC and LC II, there is a separate
- video RAM, which means that they don't suffer from waiting for the video
- the finish with the bus. On the whole, I am afraid this tips the balance
- slightly in favor of the Macs.
